Dj. Smyth et al., STRUCTURAL-CHANGE IN THE RELATIONSHIP BETWEEN PRESIDENTIAL POPULARITYAND INFLATION AND UNEMPLOYMENT - THE NIXON AND FORD PRESIDENCIES, Applied economics letters, 2(9), 1995, pp. 305-307
A quadratic presidential popularity function for the Nixon and Ford pr
esidencies is estimated. Using monthly data it is found that there is
a structural change in the relationship between presidential popularit
y and inflation and unemployment between the two presidencies. This re
sult strengthens the authors' earlier finding that one must be wary of
using a single social preference function between inflation and unemp
loyment that is time invariant.
